Apple has admitted that some of its third-generation Apple TVs have Wi-Fi issues—but owners with affected hardware are now able to exchange it for a fully functional replacement.
The affected units struggle to locate a Wi-Fi network, are sometimes unable to join a network, and experience dropped or intermittent connections, reports 9to5mac. As Apple explains:
Apple has determined that a very small number of Apple TV (3rd generation) products might experience one of these Wi-Fi related connectivity issues: Cannot locate network, Unable to join network, Dropped or intermittent connection.
Official retail stores, AppleCare employees, and authorized resellers have all been informed of the problem.
